This Invention relates to humidifying,

lheating and Ventilating systems and has for its object to provide such a system whereby the atmosphere in a mill or other room can lleading from the same or from another fanv be maintained at different temperatures or diierent humidities in two sections of the room, and whereby, for instance, a cool, moist condition is obtainable in the lower level of the room and in the upper levels a drier and warmer condition.

The invention consists in certain improvements which will be hereinafter described and fully pointed out in the claims. I In vthe accompanying drawings which form part of this specilicationz-Figure 1 represents a sectional perspective elevation of an ordinary room with a loom, such as is used in weaving ordinary cloth. Fig; 2 represents a sectional elevation of the end of the loom and the floor of the mill, showing the distributing pipe. Fig. 3 represents a sectional end elevation of Fig. 2, on line 3 3 and Fig. 4c represents a plan view of the distributer.

Reference being had to the drawings and the designating characters thereon, 1 indi- Oates a duct of galvanized iron or other suitable material for'conveying air 'from a fan or other source of supply, not shown, heated and moistened to any degree desired, -across the mill, and thence by lateral ducts 1 along or through the mill directly underneath the floor. or underneath the line of looms or other equipment which it is desired to humidify. 2 indicates a similar duct for the purpose of carrying humidiied or heated or cooled air, depending on the season of the year, to the upper ari:J of the room and thence through a distri utmg pipe extending the length of the mill provided i with lateral outlets 4.

3 indicates a temperature and humidity controller through which the air from the 'duct 1 is `forced and passed over thermoresponsive members, and by means of'which both the temperature and humidity of the air entering the duct l is controlled to any desired degree.` Such a humidity controller is illustrated and described in application for United States Letters-Patent, erial No. 607,849, as well as in Patent No. 856,944, June l1, 1907, and does not need further description here.

5 indicates the wall of the mill building l in which the equipment is designed to be operated.

6 indicates a loom, the" warp threads of which it is desired to keep moistened so as to prevent breakage of .the warp and produce. better, smoother, nicer running work.

7 indicates the beam onV which the warp threads are wound.

8 indicates the Outlet from duct 1 by means of which the humidied and treated air from duct 1 is led up through'the pipe`9 and discharged against the beam 7.

10 indicates a regulator similar to 3, and is for the purpose of controlling the humidity and temperature of the air in the room,

more especially that supplied through duct 2.

It is well known that in Weavlng operations, and especially in the operation known as jacquard Weaving, that there is great advantage or gain in keeping the warp threads damp vand moist, but this gain is often necessarilyA sacrificed on account of the detrimental elfects that occur .in the paper cardA patterns and other moisture sensitive parts of the jacquard attachment. VChanges in temperature and humidity about a jacquard are extremely undesirable and render perfect work difficult of attainment. On the, other hand', considerable `moisture around the warp threads increases production and produces a far' superior class of goods. Hence i-s seen the desirability'of maintainling a dry condition of the atmosphere in the upperportion of the room where the jacquard section is-placed, and a moist stratum of air in the lowerI part of the room where the `warp beams and threads are located. It is seen, therefore, by this double distribution of air that I have made provision for introducing through duct 1 and its lateral branches, and discharging underneath each yloom and directly against thel beam and warp threads, a blast of air which is controlledboth as to its relative humidity and n temperature by means of automatic regulator 3. Furthermore, in order to maintain a drier and a vsomewhat warmer atmospheric condition'in the upper part of the' room, air is forced throughduct 2 and distributed Voverhead and the relative humidity and the temperature of that air maintained at any desired condition by means of the regulator 10. are providedon each of the regulators ofthis type, it is therefore evident thatI can'. discharge air against the warp atany de'-- sired humidity and temperature, depending upon the setting of the regulator 3, andai-rl into the upper part of the room'at any `de"v sired humidity and temperature by mean's of the setting of the regulator 10. l

' It is evident, that this method of distribution is not necessarily confined merely t'orooms or factories wherein the weaving operation is carried on, or even limited to the use for looms; there are other manufacturing conditions where it is desirable to maintain diiferent atmospheric conditions. at the lower part of the room than at the'4 This inventiontherefore, is not limited merely to roomsupper part of the room.

where looms are operated, but is useful in any location where dierent atmospheric conditions are desired in 'different parts of the room. It is further evident that it is not essential that the one distributing duct should be located underneath the loom or beneath the floor. .It could be located above the machinery, provided suitable outlets or 'i branches were provided and the air distributed from those outlets near the floor or against the warps.

The essential feature of this invention is the multiple distribution of dierently conditioned air currents.

Having thus fully described my invention, what I claim is:

l. In a ventilatingsystem, means for sup' plying air of different qualities in diiferent planes or strata, and means for automatically regulating each supply of air.

2. In a Ventilating system', means for supplying air of predetermined humidity l/Vith the adjustments that v i Witnesses -and temperaturel in different planes or strata, and separate means for automatically regulating each supply of air.

3. A duplex Ventilating system comprising a plurality of ducts for distributing air currents having different heat and moisture properties, and means for automatically controlling the relative humidity and temperature of air supplied by each system.

4. A duplex Ventilating system comprising an upper duct and a lower duct, said ducts being adapted to carry air currents having diiferent heat and moisture properties, and means for automatically controlling the relative humidity temperature 7' of the air in each duct.

5. In a duplex Ventilating system comprising a plurality of ducts, a humidity and .temperature control for each duct, and

*.generally, and means for distributing the air from the lower system locally, and means for controlling the humidity and temperature of each current of air.

8. In a duplex humidifying and heating system, means for supplying tempered air to the upper part of a room or building, and means for supplying air with different atmospheric conditions to 'a lower part of the room or building, and means for controlling the humidity and temperature of the air in each system.

In testimony whereof I ax my signature in presence of two witnesses.
